A cup of fresh coffee is part of the morning routine for most people, but on hollidays we often use instant coffee. But why settle for less if you don’t have to. With the Rubytec Robusta Portable coffee grinder & Drip Stainless Steel coffee filter, a fresh cup of coffee is literally made in no time.
Rubytec Robusta Portable coffee grinder
The Rubytec Robusta Portable coffee grinder has a packsize of ⌀ 50 mm x 130 mm and on my precision scale I weigh 205.7 grams. Plastic is used for the grinder housing. The black plastic upper part has an anti slip structure so that it holds comfortably and the bottom part is made of smooth transparent plastic. This bottom part can be unscrewed because it is the container in which the grounded coffee falls.
The interior of the Rubytec Robusta Portable coffee grinder is made of steel, just like the turning mechanism, the handle and the grindstones. The fact that the grindstones are made of steel makes them more durable than grindstones made of plastic, as are sometimes used in cheap grinders. Ceramic is of course even more durable but also more expensive. The rotating part of the crank is made of wood that is painted black. In my opinion it could do without paint; what is wrong with the natural color of wood?
Rubytec Robusta Drip
We are not there yet with the grinder alone, no filter coffee without a coffee filter. The Rubytec Drip Stainless Steel coffee filter has a pack size of 80 mm x 120 mm by 2 mm and weighs 15.1 grams. It is made of 18/8 stainless steel. 18/8 means that 18% chromium and 8% nickel have been added to the steel alloy, making it suitable for use at high temperatures. In addition, 18/8 is also food grade steel and of course dishwasher safe. The filter is a mesh and this mesh has holes off 0.02 mm.
Depending on the beans and the type of coffee you want, first adjust the grind. You do this by unscrewing the transparent container and looking into the grinder from below. There is a kind of three-wheeled windmill. By turning this, the grindstones will be closer or further apart. This allows you to determine the size – or fineness – of the grind. The windmill has nice clicks so you can feel exactly what you are doing. With the grinder you can grind fine enough to make an espresso grind so that you can also use the coffee in a percolator. In case you don’t like filter coffee.
For daily coffee, I always use Hema Arabica beans. This is a blend of beans from South America and Africa and is Rainforest Alliance Certified (more info here www.rainforest-alliance.org) which also makes them sustainable. They would get a big 8 from me if you put price and quality together. A 1 kg bag costs € 7.50.
Grinding in practice
Making a cup of coffee is then child’s play. Remove the lid from the top of the grinder and put the beans in it. The grinder can contain about 15 grams of beans. You can take this separately or in the receptacle under the grinder. Enough for a coffee with lunch. Then put the lid and the handle back on and start grinding. Because the plastic is quite smooth with cold and slightly damp hands – despite the structure – I leave the rubber with which the handle is stored against the grinder, for extra grip. Grinding 15 grams of beans takes about 1 minute and 14 seconds if you want a fine grind. A coarse grind takes a little less time.
Filter in practice
The filter is easy to place on a mug. On either side of the Rubytec Drip Stainless Steel Coffee filter are two “wings” of spring steel. You unfold this and clamp it around the mug. The condition is that the mug is not too wide. I mainly used the filter with the Rubytec Shira Bigshot Mug – at Rubytec they have thought about things – but of course it also fits on other mugs and some thermo bottles. Using the Drip in combination with my beloved mugs from Kupilka turns out to be less convenient because the large variant is too wide and the small variant is actually too low: the filter almost hangs on the bottom of the mug.
Take your time
Finally, it is a matter of putting your coffee in the filter and taking your time to pour the water. It is important that after the first pour, you give the grind a little time to absorb the moisture before you pour the second time. Giving time makes better coffee. Once the filter has run through, you can easily knock the coffee residue out. Then rinse the filter. But only after you have finished your coffee; otherwise it just gets cold and that’s a shame. Except for the double-walled Shira Mug, by the way, because it insulates well even without a lid.
The Rubytec Robusta Portable coffee Grinder & Drip Stainless Steel coffee filter is a great solution for anyone who likes to drink a fresh cup of coffee. The fact that the grinder is made of plastic with a metal interior makes it reasonably lightweight and yet solid. That the grind can be adjusted, allows you to use it for filter coffee or espresso percolator. And for different types of beans. The grinder works fine and it is easy to use, although the grip of the plastic can be a bit rougher.
The stainless steel filter does an excellent job and the holes in the mesh are fine enough to prevent coffee grounds from ending up in your cup even with a fine grind. Be aware that the filter does not fit on all coffee cups. It is easy to clean. The price of the Rubytec Robusta Portable coffee Grinder is € 34.99 and that is fine. The price of € 16.99 for the Drip Stainless Steel coffee filter feels a bit high, but given the fact that it lasts a long time, it is justifiable. Given the price / quality ratio, I give the set 8.4 out of 10 points.
